A Plumber installs, repairs and maintains piping systems, fixtures and other plumbing equipment used for water distribution, drainage and waste disposal. Specifically, a Plumber:

  • lays out, assembles, installs, maintains and repairs piping, fixtures and other components for the supply or disposal of water for any domestic or industrial purpose
  • connects any appliance that uses water
  • installs the piping for any process, including the conveyance of gas or any tubing for a pneumatic or air-handling system
  • reads and understands design drawings, manufacturers’ literature and installation diagrams for piping and appliances

In Ontario this trade is compulsory, which means certification or registration as an apprentice is legally required to practice the trade.
